DAC60508: DAC output Filter

Aditya Patil

Part Number: DAC60508

Tool/software:

We are using "DAC60508" in our Design and Connected DAC outputs to ADC inputs of AM64x. Please confirm if any filtering circuit needed for DAC output signals before connecting it to AM64x ADC pins.

Hi Aditya,

What is the full part number for AMC64x? This question is likely less related to the DAC, and more related to the input drive requirement of the ADC. The DAC on its own should not require any filters.

Hi Katlynne,

can you help me to look for a DAC?

The VDD can be as high as 16V, and output voltage is up to 13.2V, with I2C interface, 8+ bits.

Thanks,

Tony

Hi Tony,

We do not have a DAC that meets these exact specs with I2C.

You could use the DAC60401 which will meet the output voltage range, but it does not have I2C.

You can use any I2C DAC (maybe DAC3701) and include an external gain stage to reach a 13.2V output.

Hi Katlynne,

Can you help me to find another DAC with output swing 0V to 5V, voltage offset level can be as high as 13V or even higher, I2C interface?

Thanks,

Tony

Hi Tony,

What do you mean by voltage offset level as high as 13V?

Best,
